Sacral Neuromodulation for Lower Urinary Tract Symptoms: Effect of Therapy on Saudi Patient Sexual Function

BACKGROUND: Sacral neuromodulation (SNM) is FDA-approved therapy for lower urinary tract and bowel dysfunction. It is newly introduced therapy in Saudi Arabia. AIM: To evaluate the effect of SNM therapy in both male and female Saudi patient's sexual function. METHODS: A prospective cohort study was conducted for all patients who underwent SNM implantation from January 2016 till January 2020 at a single center in Jeddah, Saudi Arabia. Sexual function was assessed before and after treatment using International Index of Erectile Function (IIEF-5) for men and the Female Sexual Function Index (FSFI) for women. MAIN OUTCOME MEASURES: Sexual function score changes from the baseline was reported. Correlation analysis was studied between IIEF-5 to assess erectile dysfunction and FSFI assessing desire, arousal, orgasm, pain and sexual satisfaction and other collected data including patient's age, functional diagnosis and post void residual (PVR). RESULTS: The study included 13 total patients (8 female, 5 male) with mean age 47y (33-60). Diagnosis included non-obstructive urine retention (5), refractory overactive bladder (3), combined retention + over active bladder (OAB) (1), pelvic pain syndrome (3) and impotence in 1 patient. All male patients showed significant improvement in their IIEF-5 score from mean pre op 7.8 ±5.7 to post op sore of 19.8±2.3 with significant p value p=0.003. Female patients showed significant improvement in their FSFI total score from baseline of 18.313±7.4 to post-operative mean FSFI score 26.7±1.8 with p value = 0.013. Domains od FSFI which showed significant improvement were desire, arousal, orgasm and sexual satisfaction with p value =0.002, p=00.1,0.012, and p=0.015. Age, functional diagnosis and PVR did not show significant correlation with IIEF-5 and FSFI score. CONCLUSION: Our results suggest that SNM might improve male and female sexual dysfunction regardless of patient's age and diagnosis. Banakhar MA, Younos A.
